THOMAS. HANLEY; OF CHICAGO, ILLINOIS cAsEimEN'r WINDOW AND HINGE'rrrnnnron Application filed December 10, 1930. Serial lNo. 501,206. l

The invention has reference. to casement ."windows or like constructionsembodying hinges adapted to permit of a dual movement of oneconstructional part relative to another. 1 w

An object of the invention is to provide a novel construction of thischaracter in which a hinge of improved character guides the movement' ofone part relative to the other in one directionandsubsequently supportssaid partduring further relative movement iii-another direction; 7 v IMore specifically stated, an object of the invention resides in theprovision of a casemer t window or similar construction in which whatmay be termed the movable closure member has a sliding movement relativet'oa frame tofr'ee the parts from an interengaging relationship'before apivotal movement of the parts is-pos'si'ble said closure memberbeingsupported by hinges fashioned to permit 'ofsuch sliding movementonly when the'parts are in their closed relationship,"and to guideandsupport the movable closure in all movements thereof relative to saidframe. J I I A further object of the invention is to pro- 'vide ahingeimember of new and improved construction for use in connection withcasemer t Windows or like structures. v

More particularly, another object is to -provide a novel hing-econstruction embody ing two hinge memberslconnected by a pintle and curlarrangement including a projecting part on the pintle-carrying memberadapted to engage :said curl to support the members in more, than'oneposition of relativepivotal movement, said members having one positionin which said curl andsaid part'are not en- ;gaged to permit of arelative movement of said members ina direction paralleling the axis ofsaid pintle. J 7

Other objects and advantageswill' become apparent in the followingdescription and from the accompanying drawing, in which: Figure l is afront elevation of a casement window construction embodying thefeaturesof the present invention.

Fig. 2 is a fragmentary front elevation, on an enlarged scale, showing ahinge-member.

Fig. 3 isa transverse section. of a hinge member showingthe parts in theposition assumed-when the window is closed.

Fig. 4 is a front elevation of 'amodifiedform of hinge.

While the invention is susceptible of various modifications andalternative construc tions, I have shown in the. drawing and will hereindescribe in detail the preferred e1n-'1" bodiment, but it is to beunderstood that Ido not thereby intend to limit the invention to thespecificform disclosed,, but intend to cover all modifications andalternative constructions falling within the spirit and scope', of"

the invention as expressed in the appended claims;

Referring more particularly to the drawring, a casement window isshown,ffor the purposes of illustration, which. comprises ail framememberlO and. a closure or .window member 11 arranged to fit relativelysnugly therein. In such constructions,the window llis' mounted-forswinging or pivotal movement relative to the frame and a common dis-,1-

advantage inherentthereto is due to thedifthe lower portion of: thewindow and the bottom portion of the frame to preventthe en'- trance ofairand moisture. In the present;v-

tionof the window and on the side thereof toward which thewindowswings.The win- .dow-receiving recess in'the frame 10 is somewhat longer thanthe window to allow the windowftoslide with respect to the frame tocarry the window free or clear, of the up- 0 per edge ofvthe stool. vThis sliding movement precedes the. pivotal movement of the window inopening it and follows such movement in closing the window.

'Means is provided in the form of binge membersfor supporting saidwindow in the a frame, which members arearranged to guide and supportthe window in its aforesald dual movement. With particularreference toFig.

2, a preferred form of hinge is illustrated as Y comprising apairof'hinge leaves orplates 13,

ficultyin adequatelysealing the gap between 14 apertured in the usualmanner to permit of their being secured to the frame and window 11respectively. One of the hinge plates, in this instance the plate 13,carries 5 laterally spaced, transversely extending bosses 15 betweenwhich a pintle 16 extends. The pintle preferably is. secured rigi'dly:to the bosses in any suitable manner as by upsetting the extending endsof the pintle; The

other hinge plate 141 carries. OHQDITIHOTG (in this instance two)transverselyextending,.

relatively narrow curls 17 which are located intermediate the ends-ofthe-iplateftowengage the pintle at spaced points between the 5 bosses15.

The arrangement and disposition of. the

Parts .i 10. tha in... a di ion -to. relative pivotal movenentof'thehinge plates, a relative sliding movementthereof,,in;adirection paralleling the pintle axis is; permitted.

When such a hinge is usedin connection with casement windowconstructions of, 1the character described, the extent of such-{slidingmovement is slightly greater than the length of movement necessary tocause the window to clear. the stool.

Means is provided; for positively, supporting the hinge plates forpivotal movement .in various of their relativeaxialpositions,

o which means is automatically engaged orfdisengaged as said plates moverelatively out of or into ,one position. In this instanc e,.this meanscomprises .one or more lugs18'formed, integrally" with thepintle-carrying plate 13 J toextend toward the pintle'into a positionwherethe curls'17 may be engaged thereby. Herein two such lugs'are shownas being located substantially centrally of one side .of the hinge plate13 and spaced'from each other 1 a, distance slightly greater than thewidth of one of the curls. '-Moreover,1ithe' lugs are so proportionedthat in. one position of the plates 18, '14 the lugs may enter the spacebetweenthe curls 17. The curls, as may be seen .1 in'Figs'Q and 3, arenot completely closed,

thereby providing gaps or recesses 19. therein througlrwhi ch tlie'lugs'18 may slide when the faces ,of the hingejplates are abutting.

Inoperation, the hinge plates. are first J properly secured tothefra'ine and window 5 such movement, acting as guides.

(see Fig. 1) so..that the faces of theplates will be in[abutment whenthe window is closed. ,As a resu'lt, the window is "free tomovevertically of the frame, the hinges, in As .the window approximatesthe top limit of its ve tica lm rem' n t cl ar the. tO lL Z, th relativeaxial movement of the hinge plates disposes one of the curls 1'7opposite the space between the lugs 18. .Uponjsubsequentpiv-Otalmovement ofthe win dow', s aid opposed lug is turned to entersaidspaceand restupon the lower lug forsupportingthe window forswingingjin 'its elevated position. It will be iden that, in thi jposion, relative axia movement of the hinge plates is positively preventedand the window is held out of contact with the stool to prevent injurythereto.

When the window is closed, the interengagement between the lugs and curlis maintained until the window is completely closed,

whereupon the recesses-19 allowthe curls to side of the window.v It is,of course, obvious .tha'toone or more than two lugs, or curls, or

both, .may be employed without materially altering the structure.

"Figure; 4 illustrates a. somewhat modified formof hinge structure. Inthisi'form, the

general arrangement of. hinge plates 13,: 14, bosses 15, pintle 16, andcurls 17isunchanged except that each curl. .has anxintermediate,.arcuately formed recess 20 therein extending from the. free endofthecurl. A single-centrally located lug21 is carried bytheihinge plate.13and is shapedand. disposed to enter one. or the. other of, saidrecesses- 20ldepending upon the axial relation of. the hinge plates.

The operation of this. formis substantially 'similarpto that of. thehingeshown in Figs-2.

.From .theIforegoing, it will bezapparent that anovel. construction fora casement window or the like has been provided which embodies an'improved .form of :hinge device adapted to guide a movement ofthehwindow in the plane thereofand.subsequently to sup- ;port the windowforpivotal movement inone V ofits .varlous. positions. Furthermore, suchoperation of the device isent1relyautomat1c.

.The structure involved is exceedingly sim ple and the hinge parts maybeformed by a die-casting operation wherebythe hinge may be manufacturedand sold at a low cost. I cla1m as myinventionz .1. A hlngecompr1s1ng,.in combination, a

-,pair of hingeplates, a pintle rigid with one of said plates, apair ofspaced-curlsonthe other of said plates engaging said pintle intermediatethe -ends thereof .to permit of .axial movement of said curls along saidpintle, and a pair of lugs on said gpintlecarrying plate extending.therefrom intothe path of axial movement of said curls,-said curlshaving recessestherein arranged in one relative plvotal position of said.plates to permit sald curls topass said lugs, said lugs being spacedapart a distance greater than the width of one of said curls'to receiveone of said curls .therebetween upon pivotal movement of said plates outof the position in which the curls may pass the lugs.

2. A hinge comprising, in combination, a pair of hinge plates, a pintlerigid with one of said plates, pintle-engaging curls carried by theother of said plates and disposed for axial sliding and pivotal movementrelative to the pintle, projecting means on the pintle-carrying platearranged to engage said curls to prevent said axial movement and tosupport said plates in several relative axially shifted positions, saidcurls having recesses therein to permit passage thereof past saidprojecting means as the plates are shifted from one to another of saidpositions.

3. A hinge comprising, in combination, a pair of hingeplates, a pintlerigid with one of said plates, pintle-engaging curls carried by theother of said plates and disposed for axial sliding and pivotal movementrelative to the pintle, projecting means on the pintlecarrying platearranged to engage said curls to prevent said axial movement when theplates are in one of several relative axially shifted positions, saidcurls being partially open to provide a recess therein through whichsaid projecting means may pass when said plates are shifted axiallywhile in faceabutting relation.

4. A hinge comprising, in combination, a pair of hinge plates, a pintlerigid with one of said plates, a curl carried by said other plate andembracing said pintle, said curl being arranged to slide axially of saidpintle and having an arcuate recess therein, and a projection on saidpintle-carrying plate fashioned to engage said recess to prevent saidaxial movement, said curl having a second and transversely extendingrecess communieating with the first mentioned recess to permitdisengagement of said projection from said arcuate recess in onerelative pivotal position of the plates.

In testimony whereof, I have hereunto alfixed my signature.
